ABSTRACT:
An arrangement for the recording of a digital information signal, in particular onto a plate-shaped, metallic recording carrier with the aid of a penetrating element is specified, in which the latter preferably has a pyramid shape with three side surfaces and three edges. The edge (6) forming the runner of the penetrating element lies, in its projection onto the recording carrier, in the direction of the velocity vector at the point of recording. The edge forms with the velocity vector an angle of >135.degree.. The projections of the two further edges onto the recording carrier lie perpendicular to the velocity vector. With the aid of such a penetrating element, an engraving of a digital signal is possible, which is read out by a laser beam.
